Loving Sleep Kube Natural Mattress — Organic Latex Hybrid | Adjustable Base Compatible
The Loving Sleep Kube Natural Mattress is one of the standout models in the Loving Sleep line and the most refined expression of natural hybrid comfort in the collection. This organic hybrid design is built for those who want genuine natural comfort paired with lasting support — and it delivers both without compromise. The construction begins with an innerspring support base, each coil secured beneath a hand laid layer of laminated cotton sheeting bonded with safe, water- based adhesives that hold the system tight and stable without any off-gassing or chemical odor. Above it, a hand laid layer of natural latex provides a feel that is both buoyant and pressure relieving — the kind of responsive comfort that synthetic foam simply cannot replicate. A natural center support zone adds extra reinforcement through the middle of the mattress where the body needs it most, ensuring consistent support from edge to center over years of use. The entire system is wrapped in a breathable organic cotton cover that keeps the sleep surface cool and fresh night after night. The Kube is also fully compatible with adjustable bases — it flexes easily without sacrificing structural integrity, making it an excellent choice for those who want the flexibility of an adjustable setup with the quality of a natural mattress. The Kube in Plush delivers the softest expression of the natural hybrid design — the latex comfort layer is tuned for a deep, cradling feel that gently envelops the body and melts away pressure points from the very first night. Ideal for side sleepers and anyone who wants a luxuriously soft surface without giving up the buoyant, supportive response that only natural latex provides. For those seeking a clean, durable, and naturally supported hybrid, this is it.

WHAT'S INSIDE OUR ORGANIC AND NATURAL MATTRESSES?
Natural Safe Ingredients Used In Our Organic And Natural Collection
NATURAL LATEX: WHERE COMFORT MEETS PURE BREATHABLE SUPPORT
Churchill & Smith uses only 100% natural Talalay and Dunlop latex—never synthetics. Natural latex is resilient, pressure-relieving, and supports proper spinal alignment by contouring to your body instead of forcing it flat. Its buoyancy promotes deeper relaxation and outlasts other materials like memory foam or innersprings. The open-cell structure keeps air flowing to prevent overheating, making it ideal for allergy sufferers. Unlike synthetic foams that trap heat and off-gas, our natural latex stays cool and fresh all night. Every Churchill & Smith mattress is built to breathe, offering long-lasting comfort, support, and a healthier sleep environment.
COTTON: NATURE'S SOFT TOUCH FOR PURE BREATHABLE COMFORT
Churchill & Smith uses a blend of organic and natural cotton for its unmatched comfort and purity. Cotton, one of the oldest known fibers, is naturally soft, breathable, and eco-friendly. We use it in our mattresses, toppers, and pillows for its durability, absorbency, and gentle feel. Cotton provides balanced density for lasting support without flattening and promotes healthy airflow to regulate body temperature and prevent overheating. Its breathability keeps your body cool and dry throughout the night. Unlike synthetics, natural cotton is hypoallergenic and dust mite resistant, making it ideal for those with allergies, asthma, or sensitive skin. Pure comfort, naturally.
POCKETED COILS: PRECISION-ENGINEERED SUPPORT FOR LASTING COMFORT
Churchill & Smith uses advanced pocketed spring coils for unmatched comfort and support. Not all coils are equal, which is why we use only top-tier patented pocket springs known for quality and consistency. Our manufacturing process eliminates leaning coils, ensuring every mattress feels balanced and supportive. Belted Pocket Spring Technology joins four coils into a QuadCoil module, maximizing stability and coil performance. The design also prevents twisting inside the pocket, reducing fabric stress and extending durability. With a center-seam closure that removes the false loft seen in standard coils, this system delivers lasting comfort, superior motion separation, and precise body contouring.
FOAM ENCASEMENT: STRONG EDGES, BETTER SUPPORT
Many of our Loving Sleep hybrids use foam encasement, a high-density polyurethane foam frame that surrounds the coil system.
This design serves two key purposes:
Stronger Edges - The foam perimeter makes the mattress feel firmer and more supportive all the way to the edge, so you don’t feel like you’re rolling off.
Tighter Coil Structure – By locking the coil unit in place, foam encasement keeps the springs firmly packed together, adding stability and overall support.
We typically use a 5-inch foam encasement around our mattresses, though it can be built in different thicknesses and heights depending on the design. The result is a more durable, supportive, and comfortable sleep surface from edge to edge.
Breathable, Supportive, and Essential
Cotton plays a key role in the Loving Sleep Collection.
We use a layer of cotton sheeting over the coils to help position them and keep the entire coil unit aligned. This layer adds structure and stability, ensuring the mattress holds its shape and support over time.
Beyond support, cotton is naturally breathable, helping regulate airflow through the mattress and contributing to a cooler, more comfortable sleep.
We also include a cotton blend center support layer, reinforcing the mattress where your body needs it most.
Cotton is simple, natural, and effective-an essential ingredient in the balance of comfort and support in every Loving Sleep mattress.

OUR SHIPPING PROCESS
BUILT SOILD, NEVER ROLLED, CURB SIDE DROP OFF
PROTECTED FOR THE JOURNEY
Built to travel safely. Every Loving Sleep mattress is built, finished, and then carefully prepared for shipping. We wrap each one in heavy duty plastic, place it in a thick gauge corrugated box, and secure it with strong straps. Whether shipped flat or folded, your mattress is fully protected and ready for the journey.
FOLDED VS ROLLED
Why some Mattresses Are Rolled and Others Are NotNot all mattresses are built the same, and neither are the ways they should be shipped.Many online mattress companies roll-pack every mattress to meet UPS and FedEx size and weight limits. To do that, the mattress has to be compressed down aggressively. In many cases, this is only possible because lighter, lower-density materials and simplified builds are used.At Loving Sleep, many of our mattresses are built with heavier, denser foams and, in some models, substantial innerspring systems. These mattresses exceed standard carrier limits and are not designed to be rolled. Rolling or over-compressing these builds would place unnecessary stress on the materials and support system.For those models, we use folding and controlled compression or local hand delivery instead. This preserves the structure of the mattress and keeps it performing the way it was intended.When rolling is appropriateWe do roll and compress mattresses when the design allows for it. Our all-foam models, even when built with higher-grade materials, can safely meet UPS and FedEx weight and size requirements without harming the mattress. In these cases, rolling and compression are simply an efficient way to ship, not a compromise in quality.The difference is the buildThe decision to roll, fold, or hand-deliver comes down to the materials, density, and support system inside the mattress. We choose the shipping method based on what best protects the mattress, not what fits a one-size-fits-all shipping box.If you ever have questions about how a specific model ships or why it’s handled a certain way, we’re always happy to explain.
CURBSIDE DELIVERY
Heavy-duty shipping, right to your curb. Because some of our mattresses are substantial and exceed UPS/FedEx weight limits, they ship through trusted freight carriers (LTL). The carrier will deliver your mattress curbside. You’ll receive a delivery window in advance, and it will require two strong people to move it from the truck into your home. This is the only way to deliver some mattresses that are heavy in weight, with complete integrity.
“We look for the best ingredients. We use nature itself. No foams, no polyurethane, no synthetics go into any of our products. Only pure natural sleep.”
—Spencer Simcik, Founder of Loving Sleep
COMPATIBLE WITH EVERY FRAME OR BASE
Loving Sleep Natural mattresses are made to work with most foundations, whether you prefer a platform bed, slatted frame, box spring, adjustable base, or a simple foundation. This flexibility means you get lasting comfort and support, no matter how your bedroom is arranged.
